6. RS232 Control
The splitter and compatible receivers feature RS232 ports to transmit RS232 signals
from computer to control far-end third-party devices by using 3-pin to DB9 cables and a
3
rd
party RS232 control software. After installing the RS232 control software, please set
the parameters of COM port number, baud rate, data bit, stop bit and parity correctly.
Compatible receivers must be able to communicate at 2400, 4800, 9600, 19200,
38400, 57600, or 115200 baud rates. The splitter requires the following communication
protocol parameters:
Baud rate:
9600 (default)
Data bit:
8
Stop bit:
1
Parity bit:
none
